The standpipe is working well, going good. The pump allows for fast truck fill, all comes down to the size of the pump.

Francis

Director - Doolee Construction

It’s exceeded our expectations. High quality, we don’t need any counter weights and it’s easy to set up. It’s been in operation for 6 months now with no hassles, we’ve got quite a substantial pump driving water to the standpipe and we haven’t any issues. Overall quality & reliability supplied by Liquimech has been very impressive.
